PAKA Mayu Ultralight Collection Launches October 2nd
PAKA just launched the Mayu Ultralight Jacket and Vest, crafted with PAKAFILL® alpaca insulation for unmatched warmth-to-weight performance. Ultralight, sustainable, and packable, the Mayu is built for travelers, hikers, and anyone chasing gram-saving gear.
Discover warmth without the weight.
PAKA has done it again! After years of pioneering with natural fibers, they’ve officially unveiled their lightest, warmest, and most sustainable outerwear yet: the Mayu Ultralight Jacket and Vest. Powered by PAKAFILL® insulation, the Mayu collection takes alpaca fiber innovation to the next level, delivering unmatched warmth-to-weight performance for outdoor adventures.
Why the Mayu Stands Out
The Mayu collection is the next evolution of PAKAFILL®, PAKA’s patented insulation made from traceable alpaca fiber. Already proven to be lighter and warmer than synthetic fills, PAKAFILL® has now been refined into ultralight outerwear that feels nearly weightless yet keeps you incredibly warm. Every stitch, trim, and zipper was redesigned to cut ounces without cutting durability.
Here’s what makes Mayu a must-have:
- Serious Warmth – With a CLO value of 1.6, the Mayu is warmer than comparable synthetics. A cinch system at the hem locks in heat.
- Sustainable Build – Recycled nylon shell and lining, PFAS-free, wind- and weather-resistant, and ethically sourced alpaca fiber.
- Built to Move – Set-in sleeves for better range of motion and glove-friendly front zip pockets.
- Packable Performance – Packs into its own chest pocket, doubling as a compact pillow for travel or camping.
Launch Details
The Mayu Ultralight collection launches October 2, 2025 at 8am PT. Available in both men’s and women’s jackets and vests, this first drop is expected to move fast.
Why PAKAFILL® Is Different
PAKAFILL® is alpaca-based insulation engineered with hollow air pockets that increase thermal retention while improving breathability. That means you stay warm in the cold and cool in the heat—making Mayu naturally thermoregulating. Alpaca fiber also boasts:
- Durability – With a tensile strength of 50 N/ktex, it’s built for long-term adventure.
- Lightness – Hollow fibers provide insulation without weight.
- Water Resistance – Warmer than down when wet, with faster drying times.
And unlike goose down, PAKAFILL® comes from free-roaming alpacas in the Andes—making it a cruelty-free insulation with real sustainability at its core.
